easy come, easy go

easy come:
nina and i are going on holidays, i paid for our tickets and yesterday evening she paid me back her half (1100$).
at least once i swam in money!
easy go:
i just got this fine (around 150$) for crossing three red lights with the bike.
it was quite funny in the end, because the police-officer looked really puzzled, when i answered “no” to his question (he asked: “will that be a lesson for you?”)
